Weyl and Dirac semimetals are three-dimensional phases of matter with gapless electronic
excitations that are protected by topology and symmetry. As three-dimensional analogs of …

Topological materials have become the focus of intense research in recent years, since they
exhibit fundamentally new physical phenomena with potential applications for novel devices …

Three-dimensional (3D) topological Dirac semimetals (TDSs) represent an unusual state of
quantum matter that can be viewed as “3D graphene.” In contrast to 2D Dirac fermions in …

Abstract A three-dimensional (3D) Dirac semimetal (SM) is the 3D analogue of graphene
having linear energy dispersion around Fermi points. Owing to the nontrivial topology of …

The last decade has witnessed great advancements in the science and engineering of
systems with unconventional band structures, seeded by studies of graphene and …

We study transport in Weyl semimetals with N isotropic Weyl nodes in the presence of
Coulomb interactions or disorder at temperature T. In the interacting clean limit, we …

From a direct calculation of the anomalous Hall conductivity and an effective
electromagnetic action obtained via Fujikawa's chiral rotation technique, we conclude that …

Cadmium arsenide (Cd 3 As 2), a time-honored and widely explored material in solid-state
physics, has recently attracted considerable attention. This was triggered by a theoretical …

The topological semimetal is a new, theoretically predicted and experimentally discovered,
topological state of matter. In one of its several realizations, the topological semimetal hosts …

We study the chiral Ising, the chiral XY, and the chiral Heisenberg models at four-loop order
with the perturbative renormalization group in 4-ε dimensions and compute critical …
